Winterising/Dry Storage

Store the boat covered in a clean, ventilated and dry place that is not affected by major 

variations in temperature or humidity.

 For full information on servicing please refer to the 

Rotax engine service manual.

Buoyancy Tube

Prior to storing over the winter periods the buoyancy tubes must be deflated and hosed down 

with fresh water, removing any small stones and weed from around them, then allowed to dry. 

Use a proprietary tube cleaner and polish to ensure optimum condition. Store with the tubes 
lightly inflated where possible.

Maintenance of the Hull & Deck

Wash the deck regularly using a mild detergent in warm water and hose down to remove 

sand etc. The hull and deck should be regularly polished using a good quality gelcoat polish to 
minimise fade and UV chalking. 

Battery

The battery used in the Minijet is of the dry cell type. This means that the electrolyte content is 

absorbed in a special fabric which requires no ‘topping up’ and is leak proof in any position. 

When the boat is not being used for an extended period of time, disconnect the earth terminal. 
A trickle-charging device, such as an 

Accumate

, will extend battery life.

Fuel System

Fuel will become stale over a period of several months. A full fuel tank prevents moisture and 

mildew from developing within the tank. Fuel begins to break down after approximately 30 

days. Adding a fuel stabilizer in the recommended ratio will minimise this.

Cooling System

Flush the open loop water circuit to remove salt, sand, shells and other contaminants that may 

be trapped in the raw water cooling circuit (refer to 

After Use: Flushing Procedure

 section).

Measure the anti-freeze content of the engine coolant with a commercially available anti-freeze 

tester. A 50/50 mixture of distilled water to propylene glycol provides sufficient frost protection 

to approx. -37°C. Run the same 50/50 antifreeze mixture through the open loop system using 

the flush attachment and a suitable container

Engine Oil Change 

It is important to change the oil. Used engine oil contains water, unburned fuel and small metal 

particles. When old oil is left in the engine for longer periods, corrosion and degradation of 

bearings within the engine may occur. 

Conserving the Cylinders

Unscrew the spark plugs and pour approximately 10ml of clean engine oil directly into each 

spark plug bore. Crank the engine a few times with the starter. Screw in the spark plugs again.

Grease Cables

Grease all control cables at both ends and exercise them to ensure good coverage

General Corrosion Protection

Use maintenance spray on key switch. Apply a proprietary corrosion guard to engine, electrical 

connections, under helm and around jet pump area.
